CHAIN CUTTER. I

' SPECIFICATION forming part of Letters Patent No. {170,103, dated March1, 1892.

Application filed August 15, 1891. Serial No. 402,740. (No model.)

To all whomzt may concern:

Be it known that I, NATHAN ALEXANDER OHANEY, acitizen of the UnitedStates, residing at Cadiz, in the county of Harrison and State of Ohio,have invented certain newand useful Improvements in Chain Cutters; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to chain cutters for boring and mortisingmachines.

The purpose of the invention is to provide a cutter of the character setforth in which the parts can be readily replaced at a small cost andremoved for purposes of sharpening.

The improvement consists of the novel features and the peculiarconstruction and combination of the parts, which will be hereinaftermore fully described and claimed, and which are shown in the annexeddrawings, in which Figure 1 is a top plan or front view of acutter-chain embodying my invention. Fig. 2 is a bottom plan or rearview of the cutterchain. Fig. 3 is a side viewof the invention. Fig. 4is a detail View of the spur-cutter. Fig. 5 is a detail view of thechisel or knife cutter.

The cutter-chain is composed of links A, spur-cutters B, and knife orchisel cutters D. The spur and the knife or chisel cutters arealternately arranged in the length of the chain and are held in place bythe same pivots or pins which hold the links together. The spur-cutteris composed of cross-bar b, of proper length, round on its front oractive side, and having spurs b at its ends and shank b projected fromits rear side, which shank is apertured to receive the pin whichconnects the links together. The spurs flare slightly from the base ofthe bar to their cutting-edges to cut a mortise which shall be slightlywider than the length of bar I) or knife or chisel cutter D, therebypreventing binding of the latter in the said mortise.

The knife or chisel cutter is composed of the blade d, which curves incross-section,

at the inner edge of the blade, which shank is apertured to receive thepin which connects the links A together. The portions of the aforesaidcutters which project on each side of the shank overlap the links andobtain a purchase thereon sufficient to hold the said cutters inposition for efficient service and project beyond the sides of the chainto prevent binding of the latter on the sides of the mortise.

The links are similarly constructed and comprise a bar, which isdeflected between its ends to bring the end portions in relativelydifferent planes, whereby when the links are assembled and connected inseries, as shown, the strain on thelinks will be practically in astraight line. Thelinks are preferably cast, although they may bedrop-forged or otherwise constructed, and are strengthened at the pointof deflection by the overlapping portion a.

In the operation of the invention the spurs cut the wood on each side ofthe mortise and the knives or chisel-cutters remove the wood between thesaid cuts. Obviously the links, the spur, and the knife or chiselcutters being independent of each other, any one can be removed andreplaced without disturbing the other.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, is-

1. A chain cutter composed of independent links, and separate spur andknife or chisel cutters, and pivots or pins connecting the links and thesaid cutters together, substantially as shown.

2-. A chain cutter composed of links, knife or chisel cutters, andspur-cutters, the latter comprising a cross-bar having spurs at itsends, and a longitudinally-apertured shank which receives the pin thatconnects the links of the chain, substantially as described.

3. A chain-cutter composed of links, and chisel or knife cutters, whichare composed of a blade curved in cross-section, and alongitudinally-apertured shank, and a pin connecting the links and thesaid cutters together, substantially as described.

4. A chain cutter composed of links, each deflected between its endslink being a bar substantially as and for the purpose described.

x o In testimony whereof I atfix my signature in presence of twowitnesses.
